Management of I/O Requests
{"Image DocumentName": "Management of I/O Requests", "Image ImageDescription": "The Device Manager divides an I/O request into three parts with each one handled by a specific software component of the I/O subsystem. The I/O traffic controller watches the status of all devices, control units, and channels. The I/O scheduler implements the policies that determine the allocation of, and access to, the devices, control units, and channels. The I/O device Handler performs the actual transfer of data and processes the device interrupts.
